round your answer to the nearest tenth.
loaves per day

Explanation:

Step1: Identify values

Wednesday: 49 loaves, Saturday:12 loaves; days between:3 (Wed→Thu→Fri→Sat: 3 intervals)

Step2: Calculate rate of change

Rate = $\frac{\text{Change in loaves}}{\text{Change in days}} = \frac{12 - 49}{3} = \frac{-37}{3} \approx -12.3$

Answer:

-12.3
